The Exchange Internet Mail Connector does not have a byte of MS Mail code in it. Exchange core has little or no MS Mail code in it. It is a completely new-generation messaging platform. It is not an incremental improvement of the MS Mail code base. And, the Internet Mail Connector is not "bolted on" to Exchange. It is a well-integrated gateway using the Exchange gateway interfaces. Finally, yes, it is a fully RFC compliant SMTP server (or gateway, if you like, in Exchange 4.0 -- in Exchange 5.0 it is fully integrated into the Exchange core, except for things like replication and routing). It has additional code to handle queuing, and periodic dial-up, gracefully, among other things. The problem with dial-up is not so much SMTP. Although SMTP has no real explicit support for periodic connections, it also does not have explicit limitations. The primary problem is that most SMTP software was not written to give periodic connections very thorough support. ----------------------------------------------------------------------------- Michael L.
